Subject: [geos-devel] GEOS 3.8.0 RC3

Hi all GEOS people,

*Especially packagers...* (This package fixes one last regression noticed in QGIS.)

3.8.0 will be released in 48 hours if no blockers are raised.

In support of that we would like
your help testing out the final project. You ll find that there are lots of performance improvements, we hope, and improved reliability in common operations.

Please report any issues you find in building or running tests on the GEOS ticket tracker https://trac.osgeo.org/geos/ or to this list.

- New things:
  - CAPI: GEOSBuildArea (#952, Even Rouault)
  - CAPI: GEOSMakeValid (#952, Even Rouault)
  - CAPI: GEOSPolygonize_valid (#727, Dan Baston)
  - CAPI: GEOSCoverageUnion (Dan Baston)
  - CAPI: GEOSCoordSeq_setXY, GEOSCoordSeq_setXYZ,
          GEOSCoordSeq_getXY, GEOSCoordSeq_getXYZ (Dan Baston)
  - CAPI: GEOSMinimumBoundingCircle (#735)
  - CAPI: GEOSGeom_createPointFromXY (Dan Baston)

- Improvements:
  - Improve overall performance by reducing of heap allocations (Dan Baston)
  - Improve performance and robustness of GEOSPointOnSurface (Martin Davis)
  - Improve performance of GEOSPolygonize for cases with many potential
    holes (#748, Dan Baston)
  - Support extended precision calculations (ttmath) and port JTS
    improvements related to extended precision (Paul Ramsey, Mateusz Loskot)
  - Improve performance of GEOSPolygonize for cases with many or complex
    shells (Dan Baston, Martin Davis)
  - Improve performance of Delaunay triangulations / Voronoi Diagrams
    (Dan Baston)
  - Improve performance of prepared geometry operations (Dan Baston)
  - Improve robustness of Delaunay triangulations (Paul Ramsey, Martin Davis)
  - Improve performance of unary union for lines (Dan Baston)
  - Improve general predicate, overlay, and buffer performance (Dan Baston, Paul Ramsey)
  - Improve cascaded union performance (Paul Ramsey, Martin Davis)
  - Allocate default GeometryFactory singleton on the stack (Sandro Mani)
  - Harmonize XML tests with JTS and harmonize cmake/autoconf
    test running (Paul Ramsey)
  - CMake modernization (Mateusz Loskot, Paul Ramsey, Dan Baston)
  - Return unique_ptr from most methods that produce a new geometry (Dan Baston)

- Changes:
  - Constructive geometry functions in CAPI now preserve SRID
    of input arguments in output (#896)
